accessibility

accessibility is a skill for Claude Code, Codex from aneja5/forge-skills. It costs 49 tokens per session (1,708 once invoked), scanned A, original, MIT.

A set of instructions for making user-facing interfaces accessible to people with disabilities, using WCAG AA as the baseline. It produces an accessibility policy and testing checklist.

In plain words
What is it for?
Use it when building or reviewing production UI, especially components such as modals, drawers, and command palettes, or when supporting government, education, healthcare, or EU customers.
Why use it?
It gives developers concrete rules for HTML meaning, keyboard use, focus, screen readers, contrast, ARIA, and reduced motion before accessibility problems reach users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

accessibility scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Accessibility

Overview

Establish WCAG AA as the baseline floor for every UI surface — before it ships. Output is .forge/accessibility.md — the semantic-HTML rules, the ARIA usage policy, keyboard navigation requirements, focus management rules, contrast policy, reduced-motion respect, and the screen-reader testing checklist. Pairs with design-system (which defines the visual tokens that meet contrast) and interaction-patterns (which defines the keyboard and focus contract).

When to Use

  • A UI surface is going to production and there's no accessibility audit
  • The product ships to EU, government, healthcare, or education customers (legal requirement)
  • A user reports that they can't use a feature with keyboard or screen reader
  • A new component category is being added (modal, drawer, command palette) and focus management is unclear
  • An existing UI is being audited and ARIA usage looks suspicious

When NOT to Use

  • Internal CLI tools or backend services with no UI
  • Throwaway prototypes that will never ship
  • Single one-line copy changes that don't touch interaction or structure

Common Rationalizations

Thought Reality
"Accessibility is a nice-to-have" It's a legal requirement in most markets (ADA in US, EAA in EU, AODA in Canada) and a usability requirement everywhere.
"We'll add it later" Retrofitting a11y costs 10x building it in. Every component pattern picked without a11y becomes a refactor.
"Our users don't need it" You don't know that — assistive tech use is often invisible. ~20% of users have a disability in some form.
"ARIA fixes everything" ARIA overuse is worse than no ARIA. Native semantic HTML always beats <div role="button">.
"Just make the visible thing look right" Screen readers see structure, not pixels. A visually-correct page can be unusable with VoiceOver.
"Color is enough to signal state" Colorblind users can't see red-vs-green; every meaningful color needs a text or icon backup.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

accessibility is a skill published in the GitHub repository aneja5/forge-skills (3 stars, last pushed 3mo ago), licensed MIT. It adds 49 tokens to every session and 1,708 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
